This text contains an up-to-date survey of theory, research and practice in environmental psychology, drawing on international literature. It adopts the perspective that physical and social factors are inextricably linked in their influence on human behaviour and experience and that the world in which we live is changed and often damaged by human action., Throughout the text, the issues which are important in contemporary psychology, such as levels of explanation, methodological diversity and the relationship between psychology and other disciplines, are brought to the fore. The text covers established areas of environmental concern and also brings together research on rarely covered topics, such as the effects of smell, colour and light, and the way in which physical environments influence social identity.
